Haptic device for manipulator and vehicle control

Abstract

An interface (101) for converting human control input gestures to telematic control signals includes a plurality of articulating arms (107, 108, 109) each mounted at a base end (113, 115, 117) to an interface base and coupled at an opposing end to a housing (106). The articulating arms are operable to permit linear translational movement of the housing in three orthogonal directions. At least one sensor (116) of a first kind is provided for measuring the linear translational movement. A pivot member (201) is disposed in the housing and is arranged to pivot about a single pivot point. A grip (102) is provided and is attached to the pivot member so that a user upon grasping the grip can cause the pivot to rotate within the housing. A button (118) is provided to switch between at least two modes, wherein when in a first mode control signals are used to control a vehicle base (502), and when in the second mode control signals are used to control a robotic arm (504) coupled to the vehicle base (502).

Description

BACKGROUND OF THE INVENTION[0001]1. Statement of the Technical Field[0002]The inventive arrangements relate to telematic control systems and methods, and more particularly to a single haptic interface and related methods that can be used to control both a vehicle base and a robotic arm coupled to the vehicle base of a robotic system.[0003]2. Description of the Related Art[0004]Robotic systems are growing increasingly common for use in areas in which a human may be subjected to dangerous or otherwise unpleasant work environments. Such applications include explosive ordinance disposal, search and rescue missions, environmental analysis or inspection at toxic sites and the like. These robotic systems are typically controlled remotely and include a vehicle base and a robotic arm mounted onto the vehicle base. The vehicle base is used to bring the robotic arm into the proximity of a target location or target object, and then the target location or target object is inspected, manipulated ...

Problems solved by technology

Such input devices are simple to use and understand, but also tend to exhibit coarse control of the vehicle base.

This is, however, inconvenient for the user and, to a degree, requires training and familiarization at two speeds rather than one.

More complex systems can include hand controllers (sometimes in the form of a pistol grip), which sense the movement by a user's hand.

For the vehicle base, however, haptic feedback tends to be quite crude, if present at all, and generally involves simply bu...
